Abstract
In recent years, destructive earthquake disasters have happened in the world. It is important to reduce the seismic response of houses in order to prevent from collapse of houses. Some control methods for seismic response of houses are developed. The oil dampers using the flow resistance of the silicon oil have been developed. In this paper, a Magnet Oil Damper (MOD) in which permanent magnets are added to the oil damper is proposed in order to improve the performance of the oil damper. The effect of MOD is examined experimentally. The damping ratio is large when MOD is used. The effectiveness of MOD is examined by simulation method. From simulation method using the analytical model, it is found that the response decreases when MOD is used.
